6    
7    checkpoint58d_post
8    o upgrade simple test-experiment to tutorial example:
9     step.1: duplicate the experiment and (step.2) will remove the old copy.
10      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
11      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
12      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
13      tutorial_global_oce_biogeo    <- copy of dic_example
14      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
15      tutorial_plume_on_slope       <- copy of plume_on_slope
16      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
17      tutorial_global_oce_optim     <- empty for now (David ?)
18      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
19     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
20    o correct a sign problem in cost_scat.F
21    o obcs and ptracers: fix boundary conditions for advections schemes
22      with larger stencil
23    o thsice adjoint: start
24    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
25      completeness
26    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
27      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
28    o ptracers adjoint:
29      * avoid extensive recomputatations
30      * fix missing re-init. of gptr (missed by TAF)
31    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
32      me to turn off the excessive output to STDOUT that this package produces
33    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
34      and add those terms in Vector-Invariant formulation.
35    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
36      if the control period (xx_hfluxperiod etc) is 0
37    o in profiles pkg, clean routines and fix details
38    o in ecco pkg, reading ssh data:
39      fix problem in case the model does not start at iter0=0
40    o fix mnc-pickup/restart for ptracers
41    o new package prifiles:
42      code to compute profile-based cost by Gael Forget
43      (modifs in ecco, ctrl, autodiff)
44    o Benign bug fix in initialization (spotted by M. Mazloff) of
45      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
46    
47    checkpoint58c_post
48    o adjoint: finish NLFS adjoint and provide reference output in
49      verification/global_ocean.90x40x15/results_ad_nlfs
50    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
51      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
52      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
53      with SEAICE_CGRID defined.
54    o move calendarDumps from "data" to "data.cal" and clean-up the code
55      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
56    o add useEXF & useCAL flags (for now, set in hard-coded way)
57    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
58      (were missing in NH mode, and wrong in quasihydrostatic mode).
59      waiting for Chris updated version of calc_gw to add those CALLs.
60    o fix bug in quasihydrostatic S/R ;
61      add a test for this option: global_ocean.90x40x15.qshyd
62    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
63      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
64    o add on/off flag useOffLine for package OFFLINE
65    o seaice:
66      - modify advection so that it works also on the C-grid
67      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
68        problem in multi-tile runs with C-grid
69      - add flags for clipping ice velocities and/or masking solver forcing
70      - fix drag (ocean on ice) formulation and a bug that caused noise in the
71        C-grid solver
72      - added a few comments to seaice_diffusion.F
73      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
74        are now exclusive)
75      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
76        required re-ordering the code a little:
77       + make DAIRN global variable (defined in SEAICE)
78       + move computation of the viscosities eta and zeta into a new separate
79         routine (because I need to recompute them in seaice_ocean_stress.F)
80    
81    checkpoint58b_post
82    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
83      update output.txt of exp. aim.5l_cs.thSI
84    o various mnc cleanups and improvements:
85      + shrink lookup tables by factor of ~4
86      + better error reporting when running out of lookup space
87      + able to handle longer path/file names (up to 500 chars)
88    o adjoint:
89      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
90      - TBD: "hidden" mom_vecinv recomp. in dynamics
91    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
92     (allow to differentiate between forcing components using new integer flags:
93      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
94     and add new flag to put Dissipation tendency out of Adams-Bashforth.
95    o ecco
96      - enable trend removal from SSH anomaly obs.
97    o adjoint
98      - a fix for PmEpR when #undef EXACT_CONSERV
99      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
100      - try to fix "hidden" recomp. in forward_step for NLFS
101        (NLFS seems broken sometimes after I checked it in)
102    o seaice:
103     - add c-grid version of the dynamic solver:
104       + three new routines that are the c-grid substitute lsr, dynsolver
105         and ostres
106       + put a few fields that were local to dynsolver into global common
107         blocks, so that I can move the computation of stresses etc into
108         seaice_lsr (saves coding but may break the adjoint).
109     - replace more hardwired parameters by runtime parameters
110     - add ice masks that mask the rhs of the implicit solvers where there
111       is no ice (commented out in seaice_dynsolver, because i am not sure
112       if this works properly), eventually this should replace the clipping
113       of ice velocities in seaice_dynsolver to +/-40cm/s.
114    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
115      include it only where its needed
116    o move balancing of fluxes before the call of external_forcing_surf
117    o seaice:
118      - correct units of turning angles (now they are really in degrees)
119      - move computation of GWATX/Y out of main routine into dynsolver
120      - initialize GWATX/Y in seaice_init
121  o Apply mask on Fresh-Water flux (needed for SSH forcing).  o Apply mask on Fresh-Water flux (needed for SSH forcing).
122    update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)    update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
123  o seaice: add runtime flags for turning angles (default to zero)  o seaice: add runtime flags for turning angles (default to zero)
124  o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean  o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
